It is widely predicted that low-lying coral reef islands will drown as a result of sea-level rise, leaving their populations as environmental refugees. But new evidence now suggests that these small islands will be more resilient to sea-level rise than we thought. That is not to say that these tiny nations wont face significant environmental challenges. Built of sand and shingle and lying just 1-3m above the current sea level, coral reef islands in the central Pacific and Indian Oceans are considered among the most vulnerable places on Earth. http://theconversation.com/dynamic-atolls-give-hope-that-pacific-islands-can-defy-sea-rise-25436 hate to break it to the Einsteins that wrote this masterpiece but Darwin explained atoll formation in 1842 http://atoll.inria.fr/~clerger/Darwin.html
